(a) Define the term 'latent heat of vaporization' of a liquid. What is the value of the latent heat of vaporization of water?(b) Draw a labeled diagram of the experimental set-up to study the latent heat of vaporization of water.

(a) The latent heat of vaporisation of a liquid is the quantity of heat in joules required to convert 1 kilogram of the liquid at its boiling point to gas or vapour, without any change in temperature.
The latent heat of vaporisation of water is 22.5 × 105 J/kg.
 (b) The labeled diagram of the experimental set-up to study the latent heat of vaporization of water is given below:
